Hi a warm welcome to the site.
If you have access
to this level 3 handbook pages 204+ will help you look at supporting children to manage their behaviour, within an enabling enviroment that involves the interaction of practitioners.
If it helps a few of the theories that you might see connections with are social learning and role modelling behaviours, behavourist approach (p.282) and positive reinforcement. Humanist and the care for children's needs.
Best wishes
